thicker blade, more light and edge blur and reduce the size of hilt and it will be perfect... :-)

^^ This. I have *always* had an issue with the saber hilts and blades we have seen in TOR thusfar. It looks too.... cut and dry? The lightsabers in BioWare's KOTOR looked a kagillion times better than what's in TOR right now. And that game is what? 200 years old now? If it isn't broke, do not fix it.
